Abstract

An indoor autonomous ventilation linkage system of a transformer substation relates to the technical field of transformer substation equipment maintenance, and is characterized in that a fan power supply air switch is connected with an automatic-manual change-over switch, the automatic-manual change-over switch is connected with a fan controller, and the fan controller is connected with a fan; the fan controller is further connected with an SF6 concentration sensor, an oxygen concentration sensor and a temperature and humidity sensor. The method has the beneficial effects that a plurality of control parameters are accessed to the fan controller to realize the start and stop of the axial flow fan, so that the automatic control of indoor environmental factors of the transformer substation is realized, and the requirements of unattended operation and safe operation of equipment are met. Manpower and material resources in the aspect of operation and maintenance are greatly reduced and saved, potential safety hazards of field work of operation and maintenance personnel are eliminated, the working efficiency of the field work of the operation and maintenance personnel is improved, safe and stable operation of equipment is guaranteed, and the normal service life of the equipment is guaranteed.

Description

Technical field [0001] The present invention relates to the maintenance technology of substation equipment, and in particular, to a substation indoor autonomous ventilation system. Background technique [0002] The substation high pressure chamber and the main transducing room are generally excessive in indoor temperature, and the temperature is more than 40 ° C will affect the equipment insulation, accelerate the equipment aging, and the equipment is safely operated. Cable trenches set in the substation, rainy water, and regional temperature differences, which is easy to cause indoor humidity, easy to cause mold and rust, etc., especially the secondary equipment for environmental requirements, equipment safety Stable operation. Substation high pressure chamber GIS equipment, the air inverse cabinet contains SF6 gas arc, insulated. Some causes of poisonous gas SF6 leaks, which brings great risks to the life safety and environment of operators. The substation is sealed in the seal...
